Request a new IP address from your ISP server

 Here's how to do it in windows:
 1. Click Start
 2. Click run
 3. In the run box type cmd.exe and click OK
 4. When the command prompt opens type the following. ENTER after each new line.

 ipconfig /flushdns
 ipconfig /release
 ipconfig /renew
 exit
 5. Erase your cookies in whatever browser you are using.

Frequently you will be assigned a new IP address when this happens. Sometime you will, sometimes you will not. If you are on a fixed IP address, this method will not work. If this works for you, you may want to save the above commands into a batch file, and just run it when you need it (our batch tipi is already posted please review it). This works if you have a Mobile Broadband connection or PPPoE .

Check If Your computer was used in your absence?

Do you want to know whether your PC was used in your absence?

How Download Managers accelerate Downloads ?

Ever used a download manager for speeding up downloads?? Most probably these are the top managers used widely-

1) Internet Download Manager( IDM )
2) Download Accelerator Plus (DAP)
3) Free download manager
4) Orbit Downloader
5) Flashget downloader
6) Limewire Downloader

Well as they say, download mangers in reality dont exaclty accelerate your downloads.. But actually perform the following tasks to optimize your connection-

-> Dynamic segmentation of file download
-> Bandwidth optimization
-> Provide additional resume capability
-> Use your tcp protocols efficiently

Whenever we download files, by default windows downloads it from beginning and in event of crash or powerloss its lost...

#Dynamic Segmentation provides breakup of a download file to breakup the files in real time thus downloading it in parts for efficiency..

#Bandwidth of your connection is optimized for judicious allocation. for example if your download speed it 200kbps, you can assign 150kbps for downoading content and 50kbps for browsing speed thus enhancing the dual capability of browsing+downloading not efficient usally in default

#Resume capabiltiy helps us resume broken downloads and files from the last point,due to the fact framented files are stored in a special #temp area, we can relink and refresh the download addresses to resume our downloads instead of starting from the beginning.

Thus we can see how download managers help us in efficiently using the network bandwidth to its optimum... It in reality cant increase the speed offered by your ISP plan, but makes sure you get the level best out of it

Bypass Software Trial Period Manually

Removing write-protection using Diskpart

With your USB drive plugged in, launch a command prompt. Do this by searching for cmd.exe in the Start menu (or Start screen in Windows 8). In Windows XP, click Start then Run, and type cmd.exe in the box.

NOTE: you may need to run Cmd.exe with administrator privileges if you see an “access is denied” message.

To do that, right-click on the shortcut and choose Run as administrator. In Windows 8, simply choose Command prompt (admin).

Now, type the following, pressing Enter after each command:

diskpart

list disk

select disk x (where x is the number of your USB flash drive – use the capacity to work out which one it is)

attributes disk clear readonly

clean

create partition primary

format fs=fat32  (you can swap fat32 for ntfs if you only need to use the drive with Windows computers)

exit

Remove write protection of your drive using regedit

In any version of Windows from XP onwards, run Regedit.exe (searching regedit will usually show the program at the top of the list).
Navigate to the following key:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Control\StorageDevicePolicies

Double-click on the WriteProtect value in the right-hand pane of Regedit.exe. Change the Value data from 1 to 0 and click OK to save the change. Close Regedit and restart your computer. Connect your USB drive again, and you should find it is no longer write protected. You can now format the drive as normal by right-clicking on it in My Computer and choosing Format.
If you can’t find StorageDevicePolicies, you can try creating a key by right-clicking in the white space in the Control folder and choosing New -> Key and carefully entering the name.

Now double-click on the new key (folder) and right-click once again and choose New -> DWORD. Name it WriteProtect and set its value to 0. Click OK, exit Regedit and reboot your computer.

Code Programmer

 Computer programming requires a code of ethics , and most of the code of conduct is adapted based on the code of ethics that is now used by a bevy of international programmers .
 Ethical code a programmer is as follows :
 1 . A programmer should not make or distribute malware .
 2 . A programmer should not write code that is hard to follow with purpose.
 3 . A programmer should not write documentation for deliberately confusing or inaccurate .
 4 . A programmer should not use this code reset by copyright unless it has purchased or been asked for permission .
 5 . Should not seek additional benefit of a project funded by the second party without permission . Professional ethics applicable to the programmer in Indonesia 36 . Should not steal software development tools in particular .
 7 . Should not receive additional funding from various external parties in a project simultaneously unless getting permission .
 8 . Should not write code that deliberately dropped another programmer's code to take advantage in raising the status .
 9 . Should not disclose sensitive data of employees in the company .
 10 . Not to be informed on the financial problems in the development of a project worker .
 11 . Never take advantage of other people's work .
 12 . Should not embarrass their profession .
 13 . Should not carelessly deny the existence of a bug in the application .
 14 . Should not introduce bugs in the software which eventually will benefit the programmer to fix bugs .
 15 . Continue to follow the development of computer science . In general , the programmer must adhere to the " Golden Rule " : Treat others as you want to be treated . If all programmers adhere to this rule , there would be no problem in the community .

Why Using Multiple Antivirus Programs is a Bad Idea

 1.They will try to kill each other. Because antivirus programs search your system for programs that are monitoring and sending information about your system, a competing antivirus program that is monitoring and sending information about your system tends to look like a virus, so it will attempt to block it and remove it.
2. They will fight over viruses. When an antivirus program encounters a virus, it removes it and quarantines it. But if a competing antivirus program sees that quarantined file and wants to remove and quarantine it in accordance with its own objectives, then it will repeatedly send reports and notifications about this virus that it is detecting, even though it is no longer actually a threat to your system. If you don’t want to continually get bogus warning messages, this will be a problem for you.
3. They will sap your power. Antivirus programs use a lot of your system memory to conduct system scans and other related operations. If you have two of these operating simultaneously,your system’s effectiveness can be greatly diminished or completely wiped out altogether, and without any benefit, since the two are performing redundant operations.

#32 How To Save Your Smart Phone From Battery Killing Applications

5 Tips to Protect Your Smartphone’s Battery

1.Go Easy on Ad-Supported Apps
Most of the applications constantly connect and reload, which is a major hit to your battery life. Not all free apps have ads; and not all paid apps are ad free. But you can count on any ad-supported app to be a major drain on your battery, especially if it’s using location-tracking to personalize the
content.

2.Beware of Apps that Use Too Many Internal Features
Ads are a particular example, but any app that uses a lot of the ‘internals’ of your phone will suck the juice right out of it. As we’ve said, GPS and other location services are a major concern, but it also goes for vibration alerts, WiFi, Bluetooth, and sensors(accelerometer, compass, etc.)

3.Don’t Allow Push Alerts
Email is great, Facebook is great, knowing the minute that there’s an update to your apps is great. Et cetera. After all, staying connected on a second-by-second basis is the reason you never let your smartphone out of your sight. Having said that, your battery might be drained twice as fast if you leave email push, social media, and/or app update notifications turned on.

4.Be Vigilant about Apps Mess with Your Display
Apps and app settings that adjust the brightness and timeout of the screen could be costing you juice. Obviously one of those bright flashlight apps is going to run your battery down, but also keep an eye on things like graphics-intensive games, e-readers, lock screen gadgets.

5.Monitor your Usage
I’ve been telling you all about apps that you should watch out for, but I’ll change course and recommend two essential types of apps that you should have installed: one to monitor your battery: ideally, with enough detail to let you know exactly what kinds of usage is most draining. And one to kill battery-sucking apps that keep running in the background. There area few apps that do both quite well; Android users should take a look at Android Assistant(which, ironically, comes in an ad-sponsored trial version).
Beware of these factors and save your battery life for long period.

#23 - 4 Ways to get Faster Boot Up Times

Step 1: Hard Disk Check Up

 Over time, your hard drives gets degraded both physically and digitally.
 It’s important to monitor your drives health. An error or damaged sector can throw software loading into an infinite loop causing long load times. To check your drive health:
 1. Click Start
 2. Choose Computer
 3. Right Click your Hard Drive
 4. Choose Properties
 5. Click Check Drives Health. After, the check up gives you repair options or a clean bill of health.
 6. Restart to get a faster boot up.

Step 2: Eliminate Startup Delay

 To get faster boot up speeds, you can cut the boot delay to 0. The delay is in place to allow your startup processes some breathing room during loading. Your default delay is 30 seconds. So, you can eliminate it for faster boot up times.
 1. Open your Start menu.
 2. Click Run
 3. In the command screen, type msconfig
 4. In the system configuration utility, click either BOOT tab.
 5. In the boot menu, change the default setting for the Time Out from 30 to 5 seconds.

Step 3: Organize your Hard Drive

 If you are looking for something in a messy room, naturally, it’s going to take you longer to find something. This is a good metaphor for a hard drive. Over time, filing system gets disorganized. Periodically, you need to reorganize this filing system on your hard drive. Luckily, Windows has a good utility called Defrag that will put your system in order.
 1.Open the Start Menu
 2. Click on My Computer
 3. Right Click your C: drive or your
 hard drive image.
 4. Scroll down to the Click Properties
 5. In the Properties Menus, Open
 the “Tools” menu.
 6. Choose Defragment.
 7. In the Disk Deframenter menu. Click on Defragment

Step 4: Remove Excess Startup

Programs, Most programs you add to your computer will opt to load when you startup your computer. Eventually you will rack up a load of programs that kill faster boot times. You need to reduce the startup programs. You can easily disable unnecessary startup programs. Here is how:
 1. Open your Start menu.
 2. Click Run
 3. Type msconfig, click Enter
 4. In the system configuration utility, click either services or startup tab.
 5. Uncheck all programs that your are no longer want to run in the background.

#22 Google does not consider the dots (.)

If we use dots in the mail address it will not consider. 

Its quite surprising and interesting. We have been using gmail since years.But you may not notice this feature.
It doesn't "recognize dots (.) in username". At gmail Log in page you can enter any number of dots in username. gmail ignores it as such.

 For example if your usenrname is xyz@gmail.com then,if you enter
 x.y.z@gmail.com
 x.....y.z@gmail.com
 xyz...@gmail.com
 or any number of dots , with same password it'll log in successfully.

 Try it.

#7 - 25 computer networking tips and tricks

Running a home network is pretty essential in this day and age.
Thankfully, modern hardware and software has reduced the complexities of configuring networks down to a few setup screens, and the relevant hardware often comes free with an internet connection.
If you have multiple computers, the chances are they're already talking to each other, either through wires or wirelessly. However, while your home network might be up and running, optimising it takes some doing. Follow our simple tips to extract the last drop of juice from your network hardware.

1. Change channel number
Wireless routers operate on a fixed channel. Since most routers ship with a pre-selected channel, the wireless signal may interfere with other routers in the vicinity that are operating on the same channel.
Changing the wireless channel from the factory default is a good starting point if your wireless signal strength is poor. 

2. Give the router space to breathe
The biggest advantage of a wireless router is that it can penetrate doors and walls – but that doesn't mean you can just stuff it next to a wall or cordless telephone, or use it as a stand for your stack of DVDs. Treat it with respect.
Try to keep it in a central location, away from other wireless devices; make sure it's not in direct sunlight; lift it off the carpet; and ensure its vents and air holes aren't covered. 

3. Improve reception 
Try as you might, you'll find it's sometimes not possible to put the router in a good spot. One way around the problem is to buy a router with multiple antennas and point them in a variety of directions covering your home.
Alternatively, if you've already got a router, check whether it's possible to upgrade its antennas to something stronger. However, don't get disheartened if your router doesn't have any antennas. A wireless repeater compatible with your router is a perfect solution. 

4. Use WEP
Running an unsecured network will earn you brownie points from neighbours and hackers with cars, but that's about it. Wireless routers support a variety of encryption methods, such as WPA and WEP, but these aren't enabled by default.
WPA2 is the most secure method at the moment, but before deciding on an encryption method, make sure your network cards and adapters support it as well. Bear in mind that older machines – and games consoles such as the Nintendo DS – don't support WPA. 

5. Restrict access to specific PCs
If you really don't want to use encryption, you can force your router to only connect to specific PCs. Your router identifies each computer by the unique MAC address of its network gear. Feed it a list of MAC addresses to connect to and you save yourself the trouble of entering a password each time you log in.
The disadvantage is that you'll have to add the MAC address of any new computer before it can get on your network – which is probably a more annoying way of getting things done. 

6. Disable SSID broadcast
All wireless routers have a Service Set Identifier (SSID) that identifies them to network computers. Routers from the same manufacturer generally ship with the same SSID; 'Netgear' or 'Cisco', for example.
You should first change the SSID to something unique to set your router apart from those of your neighbours. Then, once all your hardware has been set up, it's better to turn off broadcasting the SSID altogether. This ensures your router isn't displayed in the list of available networks, and won't be a target for potential hackers. 

7. Keep the firmware updated
Router manufacturers keep working on firmware, even after hardware has been shipped. In addition to tweaks in the user interface, new versions might make better use of the various components in the router, or add extra features.
Just like with an operating system, it's a good idea to upgrade the firmware of the router regularly – check the manufacturer's website for a new version. In the good old days, there was the risk of a botched firmware upgrade bricking your router, but it's a lot safer today. 

8. Familiarise yourself with the router manager
All routers ship with a browser based manager. To use many of the tips in this article, you'll have to log in to this interface – try typing 192.168.1.1 into your web browser for the most common location.
It's a good idea to familiarise yourself with the various options and settings you can tweak from within this software. Many routers also have detailed documentation that's updated regularly, so hunt out the latest manual online. 

9. Check your connections
There's nothing more irritating than receiving a 'cannot connect to remote machine' error. To ensure a solid connection, use Ethernet cables where possible. It's also a good idea to check the connection between the two PCs with the ping command.
To do this, simply open a command line and type, for instance, ping 192.168.1.2. You'll need to replace the address given here with that of your target machine. Ping works identically on Windows, Mac and Linux. 

10. Forward ports 

Many servers and applications – for example, file-sharing software, FTP servers and music-streaming servers – need to serve people outside the network. These applications accept connections on specific ports.
With port forwarding – check your router's interface – you can poke holes in your router and ask it to direct incoming traffic on a particular port (or, if you wish, a range of ports) to a specific computer that's on the network. 

11. Change DNS providers
DNS is what fetches you a website by translating the human-friendly address, such as www.pcplus.co.uk, into a bunch of machine-friendly numbers. It also displays the '404 page not found' error, corrects misspelt URLs and finds the fastest route to a web server that hosts the site you want to visit, along with lots of other cool things.
Generally, it's up to the ISP to put up a DNS server. However, there are other free services as well, including the likes of OpenDNS and Google Public DNS. 

12. Use USB adapters
These days, it's difficult to find a laptop or netbook without a built-in wireless module, but if you've used one, you'll know that they can't always be relied upon. Network cards with antennas are the best option, but they're really only suitable for desktops.
If you really need both mobility and assurance, make sure you get a USB adapter. Most of them ship with a Windows driver, but many work out-of-the-box on Linux as well. 

13. Enable Dynamic DNS
The Dynamic DNS feature enables you to connect to your computer remotely. Back in the day, when real-estate on the web was expensive, it was a wonderful option to show off your HTML skills and host your own website.
Now, by associating your dynamic IP address with a domain name, DDNS enables you to connect to the internet-exposed home computer from anywhere in the world. In addition to enabling the feature on your router, you'll also have to register with a dynamic DNS provider, such as DynDNS.org. 

14. Save power with Wake-on-LAN
What's the point of keeping a print server on when there's nothing to print? The smart way to save energy is to use the Wake-on- LAN feature of the network card. Thanks to this, you can put the machine to sleep after it's been configured to wake upon detecting network activity. 

15. Encrypt your online activity
With the range of snooping tools now available, it isn't safe to do anything online without covering your footprints. There are lots of tools that promise to encrypt your online activity, making it completely unintelligible to anyone who might be listening in.
Some of the best ones to try are the Enigmail plug-in for Thunderbird, Psi for Google Talk and FireGPG, available for Gmail. 

16. Get a Firewall distro
You can configure a firewall on a Windows or Linux machine, and there are also a bunch of third-party software firewalls available. However, building a firewall isn't easy. If you're serious about putting one up, download a dedicated firewall distro, such as Ebox. 

17. Install the software
Ebox is distributed as a Live CD ISO and there are VirtualBox/VMWare images as well. It's based on Ubuntu Server 8.04. You can also pull in Ebox packages to a standard Ubuntu Server 10.04 installation. You can find it at www.ebox-platform.com. 

18. Configure settings
Ebox can be adapted flexibly to your network. You can use it to restrict services that can be accessed and slice the network to keep some areas more secure than others. The distro runs a browser-based interface for adding, removing and configuring the components. 

19. Filter content
Besides the firewall, intrusion detection (via Snort) and filtering content (via DansGuardian) are two other highlights of the distro. DansGuardian can also plug into the ClamAV antivirus scanner and filter content based on known virus signatures. 

20. Exploit other features
In case you're still not satisfied, Ebox can also act as a gateway and provide a host of other services. It bundles various applications that enable you to turn your network into a VPN, host XMPP chat sessions or run a Postfix mail server, a Squid web proxy and more. 

21. Turn on UPnP
Universal Plug and Play helps smart devices that support UPnP to discover each other without any user intervention. Once turned on from within your router, UPnP enables a compatible infrared device, a Bluetooth phone or a FireWire camera to see and talk to each other. 

22. Write files remotely
The most logical use of a network is to share files. This is the job of the SMB protocol. Thanks to it, you'll be able to write files to a remote network share via Network Neighbourhood. On Linux, the SMB protocol is implemented by Samba.

23. Share printers remotely
In addition to sharing files, SMB can be used to share printers attached to a Windows machine. Once configured via the Windows Control Panel, a printer can be used to accept print orders or even be managed from a remote machine, irrespective of its operating system. 

24. Format shareable partitions as FAT
PCs running Windows can easily see each other and share files. For Linux or Mac machines, ensure the partitions are formatted with the FAT filesystem. Create them as Samba shares and they'll show up under Network Neighbourhood. 

25. Plug in USB drives
Once, if you wanted to share files on the network, a network-attached-storage, or NAS, device was the best bet. Not any more. New routers enable you to plug in one or more USB devices that are automatically accessible by all the users connected to the router.
